After analysis, it appears to be a simple CSS issue, specifically the component's background color and text color.

I think we could change https://github.com/materializecss/materialize/blob/main/sass/components/_tapTarget.scss#L39 Line 39 by:
background-color: var(--md-sys-color-primary-container);
color: var(--md-sys-color-primary);

to use the same color as the btn-floating at the bottom right of the tap component.
